Stewart Fastener J5020CH2Z Hex Cap Screw 1/2-13 X 1-1/4 Grade 2

Product Description

The STEWART FASTENER J5020CH2Z is a 1/2-13 x 1-1/4 inch hex head cap screw finished in zinc plating and manufactured to Grade 2 specifications. It features a standard 1/2-inch diameter with 13 threads per inch (UNC thread pitch) and a 1-1/4 inch grip length. The zinc coating provides basic corrosion resistance for general-purpose fastening applications. This fastener is installed by HVAC, plumbing, electrical, and mechanical trades wherever a reliable medium-strength hex head bolt is required in a non-critical structural connection.

This cap screw is suited for light to medium-duty fastening in residential and light commercial construction, equipment mounting, ductwork framing, electrical enclosure assembly, and general mechanical applications. Grade 2 hardware is appropriate for non-structural connections where high tensile strength is not a primary requirement. The zinc finish makes it a cost-effective choice for indoor and semi-protected outdoor environments where mild corrosion resistance is adequate.

Key Features

• 1/2-13 UNC thread form for compatibility with standard 1/2-inch nuts and tapped holes
• 1-1/4 inch body length suits typical panel, bracket, and equipment fastening applications
• Grade 2 carbon steel construction provides adequate strength for general-purpose use
• Zinc plating delivers basic corrosion protection in semi-exposed environments
• Hex head drive accepts standard 3/4-inch wrench or socket for fast installation

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw for use with any 1/2-inch UNC-threaded nut, washer, or tapped component following standard inch-series fastener specifications.

Installation Notes

Installation is performed by hand or with a standard 3/4-inch wrench or socket driver. De-energize any equipment and follow applicable safety lockout procedures before fastening near live electrical or mechanical components. Do not exceed the load ratings appropriate for Grade 2 fasteners in structural or safety-critical connections. Follow applicable building and mechanical codes when specifying fastener grade for the application.
